Application filed July 5, 1927. Serial No. 203,47

The present invention relates to decarbonizers for motor engines and more particularly for automobile engines, its object being the provision of a device attachable upon the intake manifold for drawing water into the manifold.

It is a known fact that large deposits of carbon are formed in the manifold and in the engine due to various causes such as imperfect combustion etc. Therefore a further object of the present invention is to devise a means whereby water may be sucked therethrough, which water is sprayed or formed into steam for dislodging carbon deposits in the intake manifold and in the engine.

A further object of the present invention is the provision of a device of the character indicated which may be used in conjunction with vacuum line or apart from it, depending upon the particular make of a given automobile engine.

A still further object of the present invention is the provision of detachable means foi` the purposes hereinabove indicated which may be simple in construction and inexpensive to manufact-ure.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangements of parts hereinafter more fully described, illustrated on the accompanying drawing and pointed out in the appended claim.

In the drawing forming a part' of this application, and in which like designating characters refer to corresponding parts throughout the several views,

Fig. 1 is a cross-sectional view longitudinally of the device showing the same in operative connection lwith respect to the vacuum line and intake manifold. f

Fig. 2 is a cross-sectional view longitudinally of the device, showing a slightly modified form thereof, illustrating another mode of its use and connection with the intake manifold; and

Fig. 3 is a cross-sectional view of the 50 modified form of the cap which may be used in connection with the present device.

Referring to the present drawing in dei tail there is shown the side of intake manifold 1() with which the present device is in 55 tended to operate. The device consists of a horizontal pipe 11. which. at one of its ends CII is externally threaded as at 12 for fitting into a threaded aperture in the intake mani fold as is obvious.

The other end of said pipe 11 is slightly enlarged and is internally threaded as at 13 for alternately receiving either the threaded end of vacuum line 14 or screw 15 for entirely filling said latter end of said pipe 11 for the purposes hereinafter described. lnt-egrally formed. with and downwardly depending from said pipe 11 is a cylindrical lug 16 which has externally threaded end 17, for receiving thereupon a union 18 which is internally threaded at its both ends. .Receivable within the other end of said union 18 is a threaded cylindrical stem 19. As is clearly seen on the drawing said cylindrical lug 16, union 18 and stem 19 are hollow providing a communication with pipe 11.

rfhe lower end of stem 19 is adapted to receive cap 20 which in its operative association with the device remains in threaded engagement with said stem 19. Centrally of the bottom of said cap 2O an aperture 21 is made through which communication of the atmosphere with the above described.

parts of the device is maintained.

For adjusting the device upon the intake Vmanifold 10, vacuum line 14 is disconnected from said intake manifold and pipe 11 is fitted into the aperture of said manifold in which the threaded end of vacuum line 14 was positioned. Thereupon said threaded end of vacuum line 14 is fitted into the other end of said pipe 11 for engaging the inwardly threaded end 13 of said pipe 11. |The other end of said vacuum line 14 is connected to the vacuum tank, not shown, in the usual manner. During the operation of the engine the vacuum created in the intake tion of the vacuum tank and will not interfere with its efficiency, in the great majority of the automobiles presently on the market. On the contrary the small amount of air taken by the intake manifold through aperture 21 and the present device in many cases ymanifold creates suction in said pipe 11 and will have beneficial result in that small quantities of air mixing with gas will add te the combustion .qualities thereof and in many instances will reduce engine troubles super- Y induced by incomplete combustion and con.-

sequent formation and .depositing of `carbon within the engine. However this is only the secondary object y of my invention, and I specify the same merely for showing that constant communication of intake manifold with the atmosphere through the medium of my device will not result in any .detriment to the eiciency or operation of the .engine in the great majority of automobiles in use.

lVhen it becomes necessary to dislodge the formations of carbon upon the inner walls of the .engine .cylinders and manifold la cup 23 containing water 24 as shown on Fig. 1, is placed beneath the device whereby the lower portion thereof, including cap 20 will entirely be submerged for the purpose that said water may be sucked into the device and into the cylinders through manifold 10. Some of said water taken in through `the device into the manifold and the remaining portions .of .the .engine will be converted into vapor and steam, which, acting upon the carbon deposits formed upon the inner walls of the engine cylinders and manifold will dislodge carbon vdeposits thereupon which will pass out together with the vapor and steam as well as gases through the exhaust. When larger amounts of water are permitted to be taken through the aperture 21 and the .device into the manifold, the engine will slightly `cool off' Ito a degree not sufficient to convert the taken water into vapor or steam, and sprayed water itself acting upon `the carbon depositswill in greater degree act upon the Vcarbon deposits to .dislodge the same from the walls .of the engine.

As above indicated there are `some automobiles, the construction and operation of which would not permit taking of the air through aperture 21 and capl 2O for the greatest .efficiency of the engine. Hence, a

solid cap 22, illustrated on Fig. 3 is provided for fitting upon the lower end of stem 19, and when it becomes necessary to pass water through the device into manifold 10 for the purposes hereinabove statedV said solid cap 22 may be removed from stem 19 and Yaperturedcap 2.() substituted so that water may be taken in through aperture 21.

In some automobiles it may be impracticable to .employ the present device for connecting the same to the 'vacuum line 14.

In this case -a threaded bore may be made in the manifold 10, apart fromvthe bore in which the threadedend of vacuum line 14 is fitted, or in other words the device may be adjusted upon the manifold without disturbing said vacuum line 14 as illustrated on F ig. 2. In that latter case the outer inwardly .threaded vend of pipe 11 is plugged by screw plug 15. Of course it is understood that solid cap 22 may be adjusted upon the lower .end of stem 19 in either of the two illustrated modes of adjustment of the device upon the manifold 10 illustrated on Figs. 1 and 2.

It is understood that cylindrical lug 16 may be made Longer so that either of the two caps 20 or l22 may be fitted at the lower end thereof, in which case union 18 land stem 19 may be eliminated. However, the main object for providing union 18 in conjunction with stem 19, resides in the fact that stems such as stem 19 of various lengths may be provided depending upon Vthe depth .of the cup holding the water and the amount of water which is desired to be lpassed to the engine.

l.While there is described herein a preferred embodiment of the present invention, itis nevertheless to be understood that minor changes lmay be made therein without departing from the spirit and scope ofthe invention as claimed.

IVhat I .claim as new is:

An automobile accessory for use in delivering fluids to the intake manifold of an automobile power plant and lwhich is formed :to serve either in conjunction with or apart from the vacuum line of the power plant, comprising a T-shaped pipe fitting, the body portion of which is substantially conical in longitudinal section for engagement at its small end with the intake manifold, the large end of the body portion of the fitting being internally threaded to receive either the end of the vacuum line or a closure plug, an internally threaded coupling, one end ofwhich engages the lateral branch of said 'T-shaped fitting, 4an apertured. cap, and a threaded stem betweenv the cap and the remaining end of the coupling, said apertured ca-p Aforming the intake for fluid drawn through the fitting and thence to the intake manifold by suction.

In testimony whereof I affix my signatl'irje.
